DEVICE FOR RETAINING SCREENS IN VJINDOVJ-CASINGS.

Specification of Letters Patent.

fiatented Dec. 21,1915.

Application filed March 21, 1914. Serial No. 826,278.

To all whom it may concern it known that I, ALBERT J. HnLvnnN, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Uklahoma, have invented certain new and useful Improvements in Devices for Betaining Screens in VVindow-Casings, of which the following is a specification.

This invention relates to devices for retaining window screens. in window holders in which the screen is held snugly in engagement with the window casing preventing the entrance of flies or the like and at the same time holding the screen rigid against displacement or from being rattled by the wind.

An object of the invention is to provide a retainer or holder for the screen permitting the latter to be actuated in a vertical. plane so as to establish. communication thereabove or below, likewise allowing the screen to swine. laterally in either direction by a very simple operation which will be obvious from the subsequent description thereof.

A further object and a still more essential one is that the device may be expeditiously applied to window screens now in use, is simple of construction, durable and one which may be associated with the screen by anyone even though the person be unskilled in the art.

Generally speaking, the device is intended for use not necessarily with screens, but as means for holding any readily movable member within a frame, such as a sliding door within a door frame, a sash within a window frame or a shutter over a window or door opening; therefore, although a screen has been shown to illustrate the application of the invention, nevertheless, any such movable member as those above referred to may be used instead of a window screen.

Other objects as well as the nature, characteristic features and scope of my invention will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring to the drawings: Figure 1 is afront elevation of a screen associated with the window casing, a portion of the screen being broken away to disclose the manner in which the same is engaged with the easing by my improved holder; Fig. 2 is a longitudinal sectional view showing the manner of connection between the screen and the window casing, the former being in a closed position; Fig. 3 is a similar view showing the screen in an open position by actuating the screen in a vertical plane; and Fig. 4 is a horizontal sectional view of the screen, the latter being shown in an open position by swinging the screen ina horizontal plane.

In the drawings wherein is illustrated the preferred embodiment of this invention in order to illustrate the application thereof a window casing 5 is provided in which is mounted windows 6 in the ordinary manner, while a hook 7 is engaged on each side of the window casing at diametrically opposite points which engages with the screen hold-er in a manner hereinafter described. The window screen which is indicated at 8 is of any ordinary form and has mounted on the inner face of the opposite sides studs 9, a pair of each being arranged on each side of the screen as shown to advantage in Fig. 1.

My improved screen retainer or holder in the present instance comprises a wire strand 10 made of any suitable material having a looped eye 11 formed on one end thereof and a looped eye 12 on the opposite end. said looped eye 11 engaging the lower of the studs 9 on each side of the window screen while the looped eye 12 engages with the lowest convolution of the elastic element 13 which in the present instance comprises an ordinary coil spring, the upper end of the latter being in engagement with one end of a second strand of wire is while the opposite end of said strand is in engagement with the stud on the upper end of the screen. A pair of these retainers are associated with each window screen, both being identical in configuration and being engaged with the hooks 7 of the screen so as to normally hold the latter in rigid engagement with the outer face of the window casing as shown to advantage in Figs. 1 and 2 so as to positively prevent the passage of flies or the like between the edges thereof and the window casing and at the same time permitting the screen to be readily detached when so desired.

In operation the strands of wire 10 are when in an inoperative position slack very slightly thereby causing pressure to be exerted on the elastic elements 13 when the strands are engaged with the hooks 7 on the opposite sides of the screen. In this position it is obvious that the screen may be readily moved in a vertical position either upwardly or downwardly by first exerting pressure on that end of the screen in the direction in which it is to be operated as forv instance in Fig. 3 the screen is shown in a slightly elevated position. In order to at tain this, pressure is first exerted on the upper end of the screen so as to move the same beyond the outer face of the window casing'and the screen then shoved upwardly in the usual manner, the tension on the strand 10 of Wire being sutiicient to retain the screen in this elevated position or in any other predetermined position either in an elevated or lowered position as is obvious. Another phase of movement provided for by this peculiar formation is that of swinging the screen in a horizontal plane by merely disengaging one of the wire strands 10 from its respective hook 7 and allowing the opposite strand and the opposite hook 7 to serve as a hinge or axis upon which the screen is swung, this position being advantageously illustrated in Fig. l of the drawings. a

It will be understood that the above deseription and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in details of construction, proportion and arrangement or the parts may be made within the scope of the appended claims and without sacrificing any of the advantages of my invention.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is: V

1. A device for retaining screens in window casings including means carried by the opposite sides of the screen for engagement with the window casing to prevent displacement of the screen, and permitting vertical and a lateral movement of said screen to establish communication through the window casing.

2. A device for retaining screens in window casings including means carried by the opposite sides of the screen for interlocking engagement with the window easing whereby movement of the screen in a vertical plane either upwardly or downwardly is permitted and movement in a horizontal plane in either direction for establishing communication through the casing at the option of the operator.

3. A device for retaining screens in window casings including a plurality of wire strands engaged with the opposite sides of the screen, elastic elements associated with said strands for permitting the same to be expanded whereby vertical and horizontal movement may be imparted to the screen for establishing communication through the window casing.

l. A device for retaining screens in window casings including a pair of hooks (arried by the opposite sides of the window casing, wire strands mounted on each side of the screen, elastic elements associated with the wire strands, the latter being in engagement with the hooks for retaining the screen snugly in engagement with the window casing, vertical actuation of the screen being permitted to establish communication thereabove or beneath when desired.

A device for retaining screens in window casings, including a hook mounted on each side of the window casing approxi mately midway its ends, a pair of wire strands attached to each side of the window screen one on each side adapted for engagement with the hook on. its respective side, a coil spring interposed between each pair of strands whereby the latter may be expanded for actuating the screen in a vertical plane or in a horizontal plane by disengaging the strand of wire on one side of the screen from its respective hook, the strand on the opposite side of its respective hook providing an axis on which the screen is operated.

In testimony whereof I afiix my signature in presence of two witnesses.
